Book Description
These specifications cover vulcanized elastomer compounds of natural rubber, reclaimed rubber, synthetic rubber, or rubberlike materials, alone or in combination, which are intended for use in manufacturing products for automotive applications. Compounds for tires, inner tubes, sponge rubber, hard rubber, belts, hose, mats, and insulated wire and cable are not included.The compounds listed in Tables 1 to 6 are of three types grouped in six classifications, based primarily on physical properties, which are prescribed in the tables. These values together with any additional requirements indicated by suffix letters in the grade designations as described in section, Types, Classes, and Grades of Compounds, define the properties of the compounds after vulcanization. These values apply to test specimens obtained from standard laboratory test slabs or blocks prepared in accordance with procedures described in the applicable ASTM methods. test results from finished products may not duplicate the values obtained from standard test specimens. When differences due to the method of processing or to the difficulty in obtaining suitable test specimens from the finished part arise, the purchaser and the supplier may agree on acceptable deviations. This can be done by comparing results of standard test specimens with those obtained on actual parts.Since it is recognized that basic requirements used mainly to classify compounds do not sufficiently describe some compositions, provision is made for added requirements which are indicated by suitable suffixes to the grade numbers. When the compounds may be used for purposes where the requirements are too specific to be prescribed in general specifications, it is advisable for the purchaser to consult the supplier to secure adjustment of the properties to suit the actual operations to which the material is to be subjected.In case of conflict between the provisions of these general specifications and those of detailed specifications for a particular product, the latter shall take precedence.These automotive classified compounds will serve many of the needs of other industries, even as SAE numbered steels are used. It must be remembered, however, that these specifications are subject to revision when required by automotive needs, and there is no assurance that the change will be acceptable to all other users.A key chart for reference use contains pertinent information and an example illustrating the use of these specifications.

Book Description
This valuable guide to compounding elastomers with precipitated silica covers principles, properties, mixing, testing and formulations from a practical perspective. This handbook and reference manual will serve those who work on part design, elastomer formulation, manufacturing and applications of elastomers. Ample discussion of compound specifications adds to the usefulness of this book to practitioners. Comparisons of carbon black and silica compounds throughout the book allow readers to select the most suitable formulation for applications ranging from tires to electrical insulation to shoe soles. The author has over forty years of experience in the rubber industry highlighted by his 39 years at the PPG Rubber Research laboratories. A highlight of the book is the inclusion of studies conducted by the author which greatly adds to the richness of the contents.

Book Description
Elastomers and Rubber Compounding Materials reviews the properties of elastomers and particular groups of ingredients and chemicals mixed into the basic elastomer to form a rubber compound. After introducing the history of rubber industry and the general properties of rubber, the book discusses the properties, classification, concentration, stabilization, modification, application, transport, and storage of latex. It presents as well the methods of production, composition, physical properties, and chemical reactions of dry rubber. The book then focuses on the production and classification of different synthetic rubbers, such as styrene-butadiene, isoprene, butadiene, ethylene-propylene, and chloroprene. It also discusses the production, properties, and applications of elastomers, vulcanization chemicals, fillers, stabilizers, plasticizers, blowing agents, and textile reinforcing materials used in formulating rubber compounds. This book will be of great value not only to those who are in the rubber industry, but also to students of polymer science and rubber technology.

Book Description
This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. NOTE 1:The SAE Committee on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.30 on Classification of Rubber Compounds with the goal to keep SAE J200 and ASTM D 2000 technically equivalent. Candidate materials presented for development of new tables or for inclusion in Tables A1 or A2 of SAE J200 or Table X1.1 of ASTM D 2000 shall be initiated with the SAE CARS Committee. The procedure to be followed is detailed in Appendix C of SAE J200. NOTE 2:This document may serve many of the needs of other industries in much the same manner as SAE numbered steels. It must be remembered, however, that this system is subject to revision when required by automotive needs. It is recommended that the latest revision always be used. This document is based on the premise that all rubber materials intended for use in rubber products can be arranged into characteristic designations. These designations are determined by types, based on resistance to heat aging, and classes, based on resistance to swelling by oil. Basic levels are thus established which, together with values describing additional requirements, permit complete description of the quality of all rubber materials. In all cases where provisions of this document would conflict with those of the detailed specifications for a particular product, the latter shall take precedence. NOTE 3:When the rubber product is to be used for purposes where the requirements are too specific to be completely prescribed by this classification system, it is necessary for the purchaser to consult the supplier in advance to establish the appropriate properties, test methods, and specification test limits.
